PC DDR4-SDRAM, the successor standard for DDR3-SDRAM, which continues increasing memory bandwidths while maintaining the same electrical footprints, surfaced on JEDEC roadmaps, at a recent MemCon conference in Tokyo, Japan. Just the target clock speed range for DDR2-SDRAM was 400~1066 MHz, and that of DDR3-SDRAM is 1066~2133 MHz, the DDR4-SDRAM standard will aim for clock speeds between 2133 and 4266 MHz, with DRAM voltages of 1.1~1.2V, the voltages standards-compliant DDR3 memory will ultimately end up with. Some of the first DDR4 memory chips will be built on the 32 nm or 36 nm manufacturing processes. JEDEC expects sampling of the new memory type to start in 2011 for the industry to come up with appropriate memory controllers and deployment platforms, while actual mass production is slated by 2015.

hmmmm, when they increase the speed doesn't that mean that they will also increase the timing rather than making it tighter ?

Anyway, since they will release this in 2015 I can imagine myself getting them in 2016~2018 because the same thing that happened with the DDR3 will happen again, I mean they will be extremely expensive, so I'll wait 2 o r 3 more years until I buy some of them.

Way to announce something that is 4+ years away. Totally not the same amount of time is given to let it sink in versus other technology that gets announced....like graphics or processors.
I still have yet to jump off my DDR2 s775 platform!

I have to admit i kinda hoped that ddr4 would be nothing special and that it would give a reason to jump stright to ddr5 like what happened with graphics cards, admitdly yes its way over the top for most current cpu tasks but i would assume with things like fusion/gpu intergration into the cpu die the need for much faster and higher bandwith with cpu memory woudl be very importaint
